      [ARM] 2890/1: OMAP 1/4: Update omap1 specific files, take 2 · 7c38cf02
      由 Tony Lindgren 提交于 
      Patch from Tony Lindgren

This patch syncs the mainline kernel with linux-omap tree.
The highlights of the patch are:
- Convert more drivers to register resources in board-*.c to take
  advantage of the driver model by David Brownell and Ladislav Michl
- Use set_irq_type() for GPIO interrupts instead of
  omap_set_gpio_edge_ctrl() by David Brownell
- Add minimal support for handling optional add-on boards, such as
  OSK Mistral board with LCD and keypad, by David Brownell
- Minimal support for loading functions to SRAM by Tony Lindgren
- Wake up from serial port by muxing RX lines temporarily into GPIO
  interrupts by Tony Lindgren
- 32KHz sched_clock by Tony Lindgren and Juha Yrjola

      [PATCH] Make sparc64 use setup-res.c · 085ae41f
      由 David S. Miller 提交于 
      There were three changes necessary in order to allow
sparc64 to use setup-res.c:

1) Sparc64 roots the PCI I/O and MEM address space using
   parent resources contained in the PCI controller structure.
   I'm actually surprised no other platforms do this, especially
   ones like Alpha and PPC{,64}.  These resources get linked into the
   iomem/ioport tree when PCI controllers are probed.

   So the hierarchy looks like this:

   iomem --|
	   PCI controller 1 MEM space --|
				        device 1
					device 2
					etc.
	   PCI controller 2 MEM space --|
				        ...
   ioport --|
            PCI controller 1 IO space --|
					...
            PCI controller 2 IO space --|
					...

   You get the idea.  The drivers/pci/setup-res.c code allocates
   using plain iomem_space and ioport_space as the root, so that
   wouldn't work with the above setup.

   So I added a pcibios_select_root() that is used to handle this.
   It uses the PCI controller struct's io_space and mem_space on
   sparc64, and io{port,mem}_resource on every other platform to
   keep current behavior.

2) quirk_io_region() is buggy.  It takes in raw BUS view addresses
   and tries to use them as a PCI resource.

   pci_claim_resource() expects the resource to be fully formed when
   it gets called.  The sparc64 implementation would do the translation
   but that's absolutely wrong, because if the same resource gets
   released then re-claimed we'll adjust things twice.

   So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource()
   conversion before passing it on to pci_claim_resource().

3) I was mistakedly __init'ing the function methods the PCI controller
   drivers provide on sparc64 to implement some parts of these
   routines.  This was, of course, easy to fix.

So we end up with the following, and that nasty SPARC64 makefile
ifdef in drivers/pci/Makefile is finally zapped.

      [PATCH] PCI: restore BAR values after D3hot->D0 for devices that need it · 064b53db
      由 John W. Linville 提交于 
      Some PCI devices (e.g. 3c905B, 3c556B) lose all configuration
(including BARs) when transitioning from D3hot->D0.  This leaves such
a device in an inaccessible state.  The patch below causes the BARs
to be restored when enabling such a device, so that its driver will
be able to access it.

The patch also adds pci_restore_bars as a new global symbol, and adds a
correpsonding EXPORT_SYMBOL_GPL for that.

Some firmware (e.g. Thinkpad T21) leaves devices in D3hot after a
(re)boot.  Most drivers call pci_enable_device very early, so devices
left in D3hot that lose configuration during the D3hot->D0 transition
will be inaccessible to their drivers.

Drivers could be modified to account for this, but it would
be difficult to know which drivers need modification.  This is
especially true since often many devices are covered by the same
driver.  It likely would be necessary to replicate code across dozens
of drivers.

The patch below should trigger only when transitioning from D3hot->D0
(or at boot), and only for devices that have the "no soft reset" bit
cleared in the PM control register.  I believe it is safe to include
this patch as part of the PCI infrastructure.

The cleanest implementation of pci_restore_bars was to call
pci_update_resource.  Unfortunately, that does not currently exist
for the sparc64 architecture.  The patch below includes a null
implemenation of pci_update_resource for sparc64.

Some have expressed interest in making general use of the the
pci_restore_bars function, so that has been exported to GPL licensed
modules.

      [SPARC64]: Inline membar()'s again. · 4d803fcd
      由 David S. Miller 提交于 
      Since GCC has to emit a call and a delay slot to the
out-of-line "membar" routines in arch/sparc64/lib/mb.S
it is much better to just do the necessary predicted
branch inline instead as:

	ba,pt	%xcc, 1f
	 membar	#whatever
1:

instead of the current:

	call	membar_foo
	 dslot

because this way GCC is not required to allocate a stack
frame if the function can be a leaf function.

This also makes this bug fix easier to backport to 2.4.x
